They posted a partial retraction in the editor’s note. It wouldn’t make any sense to retract the full article, since it mostly wasn’t about PropOrNot.
There was wide scale Russian involvement in manipulating the US election, not only in hacking various Dem. and Dem. organization’s systems, exfiltrating data, and using that data to attack Dems. (not just Clinton, BTW), but also in many and various kinds of manipulation of public opinion which that WaPo article discussed.
Because of that very ugly, but real situation, the public response is not going to be measured. This isn’t because they’ve “slithered to the right,” but because the US has been attacked by a hostile foreign nation’s cyberwarfare divisions to manipulate an election. That’s a really huge fucking deal. It bears repeating that that’s a really huge fucking deal. It’s a really huge fucking deal for which there’s abundant reliable evidence available to anyone who cares to check. The situation is not only shocking, but very dangerous, and infuriating to many. Given the seriousness, dangerous precedent, and results of that cyerwarfare attack, some people are losing their grip, no doubt, but this isn’t about redbaiting, but a response to very real, very serious events that just happened involving a Russian cyberwarfare attack on the US.
